REVOLVING STOVE GRATE.

SPECIFICATION forming To aZZ whom it may concern;

Be it known that I,.GErARLns KEMMERLING, a citizen of the United States, residing at the city of Scranton, county of Lackawanna, State of Pennsylvania, have invented a new and useful Improvement in Revoluble Stove-Grates, of which the following is a specification.

This improvement relates more particularly to rotating grates of which two or more sec tions are suspended in the base of the fire-pot section of the stove, and by suitable gear or equivalent connection are simultaneously revolved or shaken.

The object of the improvement is to furnish a light and effective revolving grate, not liable to burn out, easily molded, and requiring but little fitting to adapt it for the purpose designed.

The accompanying drawings, forming a part of this specification, discloses the nature of my improvement.

Like parts are designated by letters of similar character,

Figure l is a perspective view of two sections of the grate,with gear and crank. Fig. 2 is an elevation of one grate, partly in section.

A represents the end or journal disks; B, the intermediate disks or bars; 0, the journals; D, the gearing; E, the crank F, the longitudinal grate-bars G, the drag of the flask; H, the sand of the mold.

I am aware that I am not the first to produce a revolving grate adapted to .be used for stoves, ranges, 8m, but in all of which I have knowledge that the grates are heavy, exposing large masses of metal with comparatively small air-spaces, and are rapidly burned out, while others,in the act of revolving or shaking, grasp the cinders between their interlocking or projected jaws and require a powerful leverage to operate, with great risk of breaking the grate.

My grate overcomes the above objections, as it is so constructed that the air has free circulation through and around the same. The ends of the gratesections next to the frame may be plain circular disks, or they may have their peripheries cut away, as shown, to which form part of Letters Patent No. 283,790, dated August 28, 1883. Application filed Apribll, 188 3. (No model.)

I give preference. From these disks are projected outwardly shafts or journals adapted to carry at one end of each' the gearing for re;

volving the same, and at the opposite end one journal of the set will extend through the easing or within reach of a lever or crank and will be squared up to fit the same. mediate or transverse bars of the grate are a series of disks similar in formto-the end disks, and are properly spaced between the same. The longitudinal bars are arranged as shown, and are permanently secured to the end disks and to the intermediate disks spaced between the same.

The operation of the grate is as follows: If more than two sections are required to fill out the fire-pot base, then a counter-gear must be placed between each pair, so that on turning any of the series all of thegrates shall in pairs revolve toward or from each other simultaneously, according as the crank is manipulated.

The grates may be shaken or revolved and left in any position without danger of burning The interor of dropping the fire, and may consequently The grates are easily applied, and are adapted 'to both stove, range, and boiler-furnace purposes, and, having no isolated projecting parts,are dumped or agitated with ease.

Having shown the advantages of my grate, its construction, and application, I desire to secure by Letters Patent the following claim thereon: I

As a new article of manufacture, a revoluble stove-grate, as described, consisting of end disks provided with outwardly-extending shafts or journals and intermediate disks of similar form, said end and intermediate disks being connected at four or more points on the peripheries of each by longitudinal bars and adapted by gearing and lever or crank to be shaken or revolved, as and for the purpose set forth.
